Description

XsltBuilder.getSource(Exchange e, Object o) tries to convert the payload to a Source.

If you have a byte[] payload, then the following type converter will likely be picked:

InstanceMethodTypeConverter: public javax.xml.transform.sax.SAXSource 
org.apache.camel.converter.jaxp.XmlConverter.toSAXSource(byte[],org.apache.camel.Exchange) 
throws java.io.IOException,org.xml.sax.SAXException,javax.xml.transform.TransformerException

This type converter requires the Exchange (InstanceMethodTypeConverter.useExchange == true), but line 461 of XsltBuilder doesn't pass it on.

Therefore, a NullPointerException happens because the conversion method tries to access the Exchange.
